Was wondering if I was the only one with this issue. Whenever I try to load Clockwork Empires from Steam's Big Picture mode, it kills Big Picture mode and jumps back to the desktop. Loads just fine from desktop mode.
It seems the launcher itself doesn't play well with the big picture mode just yet. Perhaps it'll work later on if we get the option to start without it? It happens with a few other launcher-based games I have as well. Big picture mode seems to want to just.. 'go', without any fiddling with options.
